Abstract

The utility model relates to an impacting-cutting disc for transmitting impact power directly by using a spring. The external edge of a rotating disc is provided with three drill rods with drill sleeves; two pendulum bobs are symmetrically arranged along a driving shaft on which a vertical rod is arranged; a spring on the vertical rod is connected with a spring fixed ring which is connected with the pendulum bobs through connection pieces; a hammer handle is movably connected on the driving shaft; the rotating disc is provided with an anticollision bolt; the front part of the drill rod is provided with a returning spring; and the rear part of the drill sleeve is provided with balls. Due to the adoption of the structure, the impacting-cutting disc for transmitting impact power directly by using the spring can form large impact power without large power, and can obtain the impact power without other transferring devices, thereby reducing cost and improving efficiency; the impact cutting is performed at an angle of 45 degrees between the drill rods and a rock surface, thereby having good damage effect on the rock surface, and the impacting-cutting disc for transmitting power directly by using the spring is suitable for rocks of various hardness, and has small violation; the impacting-cutting disc for transmitting power directly by using the spring does not need large vertical push force on an influenced rock surface, and can manufacture various electric hammers, electric picks, electric hammer drills which work by using impact power.

Description

Directly transmit hitting of ballistic work and cut dish with spring

Technical field

The utility model relates to a kind of mining machinery, particularly a kind ofly is used for hitting of broken coal petrography and cuts device.

Background technology

At present, existing to scar directly with the following manner that has of mechanical damage; A kind of be the vertical thrust of the scar of input torque and effect directly to scar carry out the electric drill of cutting damage, general hitting of development machine cut head, all needs very big torque and perpendicular to the very big thrust of scar; Another kind is electric hammer, electric pick, the pneumatic pick that scar is carried out impact damage by ballistic work; The third is that above-mentioned two kinds of modes impact and rotate destroy pneumatic, the hammer drill that surges, Churn drill to scar.The acquisition of the two kinds of ballistic works in back is the conversions by air compressor and hydraulic pump process kinetic energy, produce gas, the liquid of big pressure, produce ballistic work through pneumatic, the hammer drill that surges again, when changing, kinetic energy to drop into a large amount of equipment, pipeline, the loss that other adds pipeline causes the waste of the energy, equipment, and effective power is not high.Churn drill is that beating of gear reaches impact effect, is in addition to spur impact block back and forth or the rotation by eccentric block reaches impact effect by bent axle, and its impact effect is little, and the power of its backhaul is all wasted.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, cost is low, high efficiency, impact effect are good directly transmits hitting of ballistic work with spring and cuts dish.

The purpose of this utility model is achieved in that the hammer drills that three band drill sleeves are arranged on the outer of rolling disc, two pendulums are along the power transmission shaft symmetric arrangement, vertical rod is arranged on the power transmission shaft, spring in the vertical rod connects the spring retainer ring, the spring retainer ring connects pendulum by connector, and hammer handle is movably connected on the power transmission shaft, and crashproof latch is arranged on the rolling disc, there is back-moving spring the hammer drill front portion, and there is ball at the drill sleeve rear portion.

Principle of the present utility model is; 1, length official post spring elongation the carrying out energy storage of the circular arc of the concentric garden of different radii generation when rotating synchronously discharges the function that impact is realized in the back.2, utilize the characteristic of spring,, in its retraction process, realize the function of bump with pendulum because of kinetic energy makes spring elongation energy reserve.3, during energy storage, the power that pendulum Zuo Yong Zai Brazing puts makes rotating disk produce torque force, and Shi Xian Brazing hits continuously and cuts or the direct function of cutting.4,, Brazing and scar are miter angle and scar is hit cut destruction, increase the effect of destroying.

Because the utility model adopts said structure, does not need big power can form big ballistic work, the acquisition of ballistic work does not need other transferring equipment, reduces cost, and raises the efficiency; Brazing and scar are miter angle and hit and cut, and be good to the scar execution, can be useful for the lithology of various hardness, vibrates little; Scar to effect does not need great normal thrust, directly can make various electric hammer, electric pick, electric rock drills with the ballistic work operation with the device of spring transmission ballistic work.

Fig. 2 is a fundamental diagram of the present utility model.

1 hammer drill, 2 back-moving springs, 3 drill sleeves, 4 pendulums, 5 crashproof latches, 6 spring retainer rings, 7 springs, 8 power transmission shafts, 9 hammer handles, 10 connectors, 11 rolling discs, 12 vertical rods, 13 balls among the figure.

The specific embodiment

Embodiment: the hammer drill 1 that three band drill sleeves 3 are arranged on the outer of rolling disc 11, two pendulums 4 are along power transmission shaft 11 symmetric arrangement, vertical rod 12 is arranged on the power transmission shaft 8, spring 7 in the vertical rod 12 connects spring retainer ring 6, spring retainer ring 6 connects pendulum 4 by connector 10, and hammer handle 9 is movably connected on the power transmission shaft 8, and crashproof latch 5 is arranged on the rolling disc 11, there is back-moving spring 2 hammer drill 1 front portion, and there is ball 13 at drill sleeve 3 rear portions.

Power transmission shaft 8 directly hauls spring 7, spring 7 directly hauls pendulum 4, pendulum 4 is obstructed Yin Brazing cover 3 can't make circle swing, power transmission shaft 8 continues to haul spring 7 rotations, make spring 7 elongation carrying out energy storage, simultaneously power transmission shaft 8 haul pendulum 4 to axis direction Hua Dong when Brazing cover 3 can't stop pendulum 4, pendulum 4 is hauled along the center of circle of pendulum 4 by the spring 7 of the sufficient energy of storage and makes circumferencial direction high speed swinging Zhuan Ji Brazing 1, reaches impact effect.Brazing 1 is designed to three along rolling disc 11 cylindrical tangent lines layout, and pendulum is designed to two along power transmission shaft 11 symmetric arrangement, can reach the purpose of continuous work done.Pendulum 4 is the power on the Zuo Yong Yu Brazing cover 3 when energy storage, can drive rolling disc 11 rotations, produces torque ， Shi Brazing 1 and directly act on scar, in the time of can realizing that lithology is hard, scar is directly cut, and when lithology is hard, scar is hit cut.Help sliding ball 13 in order to make pendulum 4 slide the position design that reduces resistance and frictional force Zai Brazing cover 3 close axle center to axis direction.When Brazing 1 does not contact scar; Brazing 1 ejects because of the back-moving spring 2 that is enclosed within the outside, make pendulum 4 can not hit the Brazing tail; when Brazing 1 rotates the contact scar because of rolling disc 11, back-moving spring 2 Ding Bu lives in Brazing 1 Shi Brazing 1 withdrawal makes pendulum 4 to eject in the process of withdrawal Dao Brazing tail Zai Brazing 1 by Zhuan, driving the crashproof latch 5 of design in rolling disc 11 outsides inserts and extracts by the direction of axle, crashproof latch 5 inserts rolling disc 11 inside, make pendulum 4 shock-free spaces, can't impact acting, can only be in the energy storage state.Crashproof latch 5 is extracted, and pendulum 4 has had the space of impact activity just can impact acting, hits and hits the Brazing tail.
